If you use a third nvidia as an physics card can you utilize it's DP?

[notigg]

this might be a dumb question but say I have 2 GTX 580 in SLI... if I throw in a third nvidia card... a gtx 550 .. and set it to physics can I still use it's display port but powered by the other two cards?

You probably couldn't. You most likely won't get a definitive answer because most people don't use dedicated physx cards anymore.

Modern GPU's can handle physx duties and graphics duties at the same time, SLI GTX 580's could handle any sort of Physx and the visual settings in any game anyway.

Adding a physx card would most likely slow them down.

I remember seeing some benchmarks showing a GTS 250 being all you needed for Physx. Seeing as SLI GTX 580's are at least six times faster then one GTS 250 you can see how easy it is for them to handle it.

Adding to the fact that Physx games are so few and far between there arn't many people who would make a system like that anymore.

I doubt you can because the physx card is meant to calculate and then feed the output to your main cards. For this to work, the 580s would need to push their data through your puny 550.

Adding a physx card to that setup will likely slow you down, not speed you up (the 580s would need to wait for the 550 to finish.)

Don't bother. Your 580x2 will handle anything you throw at them, PhysX or not.
